drm: Atomic modeset ioctl
The atomic modeset ioctl can be used to push any number of new values
for object properties. The driver can then check the full device
configuration as single unit, and try to apply the changes atomically.
The ioctl simply takes a list of object IDs and property IDs and their
values.
Originally based on a patch from Ville Syrjälä, although it has mutated
(mutilated?) enough since then that you probably shouldn't blame it on
him ;-)
The atomic support is hidden behind the DRM_CLIENT_CAP_ATOMIC cap (to
protect legacy userspace) and drm.atomic module param (for now).
v2: Check for file_priv->atomic to make sure we only allow userspace
in-the-know to use atomic.
